p.s. I should have mentioned that the Dragonfly works fine with NeutronMP and my Kindle Fire, but not with my Blackberry Passport (international version). I have been told that USB OTG does work on the device, and there are a few Fiio models that work correctly.

Hello, is the Chord Mojo correctly recognized by Neutron with the latest update? I would like to buy the Chord Mojo but before buying it I'd like to know if there is still the fixed frequency bug with Neutron.
Thank you,

This is the HTC 3.5 mm to USB C DAC and I use an HTC U11+. The app detects the DAC, but there is no sound when activating direct usb access. Also, I obtained this code by using USB Device Info app. Is this enough information?

The "ess sabre" is an internal DAC, not an external USB DAC, correct ?
This topic here has been created for external devices of type "USB DAC".
I suggest you either open a new topic or post into "Hi-Res Audio for Android devices" :

Since 1.97.0 version Neutron supports Hi-Res Audio output to the mobile devices which support it and have dedicated on-board DAC (ESS, XMOS, Qualcomm, ...) for Hi-Res Audio. The Hi-Res Audio must be supported by firmware of course. Minimum Android OS version is 4.4.

To make sure you have guaranteed Hi-Res Audio output (if device supports it) there are number of prerequisites in Neutron's settings -> Audio Hardware:
